****ing women. This is why you boggle us.
HE WAS HOLDING YOUR HAND BECAUSE HE WANTED TO HOLD YOUR HAND.
Men are really simple. Like, ridiculously simple. Most of us don't have an agenda, hate the 'hard to get' game and all the playing and hinting that comes from relationships. The truth of the matter is, we usually have no clue.
If you have sex with someone, regardless of how 'one night standish' the encounter is, you feel some connection. He held your hand because, ****, why not. He's already held onto every other part of your body.
If your question is 'do guys like holding hands after sex'.. well.. its a bit ridiculous. I've held hands after sex, yeah.
So, in answer to your question- men can hold hands after sex, and some will. If they want to. Mystery solved.
